IPC: B21D9/18
Filed: 1982-08-06
Abstract: PURPOSE:To reduce loads placed on rolls when an elbow is cut by providing two induction heating coils and arranging the rolls between them when heating a pipe by the induction heating coils and forming it into the elbow by an L-shaped die. CONSTITUTION:The pipe 7 is heated by the induction heating coils and while it is further heated by a gas burner 6, the L-shaped die 1 is fitted in and passed through the pipe 7 to form the elbow 8, which is cut by a cutting machine 4. In this case, two separate coils are provided as the induction heating coils and the rolls 20 and 21 for holding the pipe 7 are provided between the coils.

Title: Instrument for measuring configuration of particle in gas
Inventor: YOSHIYAMA SHUSUKE
IPC: G01N29/02
Filed: 1987-06-01
Abstract: PURPOSE:To enable the configurations of particles in a gas to be continuously measured by revolving the polarized nonspherical particles in a revolving electric field and detecting a sound wave generated at this time by a highly sensitive microphone. CONSTITUTION:The inner pipe 2 of a specimen introducing pipe 1 is connected to a duct for a gas to be measured. When a suction unit 7 is operated, the gas to be measured and the filtered clean gas are sucked-in from the distal end of the inner pipe 2 and the conduit pipe 3' of an outer pipe 3, respectively, by a suction pump 8 and the gas to be measured flows into an analyzing chamber 4. A high voltage with a positive polarity and a high voltage with a negative polarity are applied to two electrodes 5 respectively opposing to each other via a revolving electric field generator 6 in the analyzing chamber 4. Particles in the gas to be measured flowing into the analyzing chamber 4 are polarized such that each particle attracts another particle having a reverse polarity when the gas flows into the chamber 4. Since the polarity of each particle is changed to that of the adjacent particle at the next moment, the polarized particle changes an angle by being affected by the adjacent particle and then further changes the angle. Thus, the particles are revolved and generates a sound wave. The sound wave is caught by a microphone 10 and analyzed by a waveform analyzer 12 to obtain the configurations of the particles.

Title: Exhaust reflux control device for internal combustion engine
Inventor: KAKIZAKI SHIGEAKI
IPC: F02M25/07
Filed: 1995-06-05
Abstract: PURPOSE: To improve responsiveness of exhaust reflux control and prevent occurrence of malfunction of a motor by setting a driving frequency of a step motor high when pressure difference across an exhaust circulation valve is small. CONSTITUTION: Pressure difference across an exhaust reflux valve 5 is sensed by means of a pressure difference sensor 18. A coil temperature sensor 19 senses a temperature of a coil of a step motor 6. In an exhaust reflux valve 5 with the step motor 6 being an actuator, a reference frequency is set higher in a table as the pressure difference across the exhaust circulation valve 5 is small. As the coil temperature sensed by the coil temperature sensor 19 is high, maintenance current to be supplied to the step motor at the stoppage of the exhaust reflux valve 5 based on the coil temperature is set higher. The reference frequency is corrected to be a smaller value.

IPC: H02N2/00
Filed: 1994-05-27
Abstract: PURPOSE:To stabilize an operation at the time of high-resolution positioning by eliminating load wiring not to be ignored at the time of precise positioning by controlling a driving circuit with no contact. CONSTITUTION:An ultrasonic linear motor is integrated inside a fixed part 1 and a part 2 to be driven is driven in the direction of an arrow. Then, light receiving parts 4 and 5 of phototransistors are fitted on the side face of the fixed part 1 and connected to the driving circuit inside the fixed part 1. In this case, the structure/operation of this ultrasonic linear motor is similar to the conventional technique. Further, two LEDs 6 and 7 are fitted at positions facing to the light receiving parts 4 and 5 on a controller 3, the optical signal of the LED 6 is made incident to the light receiving part 4 and the optical signal of the LED 7 is made incident to the light receiving part 5 respectively. At such a time, however, optical filters with different passing wavelengths are provided so that both the signals can not be mixed. Thus, since the driving circuit is controlled with no contact, the load due to wiring not to be ignored at the time of precise positioning is eliminated.

Abstract: PURPOSE:To improve startability and dissolve an unsatisfactory start when unsatisfactory start occurs such as a warm lock by continuing/discontinuing the torque applying action in the positive rotation direction of an engine by a starting means when the unsatisfactory start state is detected. CONSTITUTION:When the starter switch 7b of an IG switch 7 is turned on, an ECU 6 outputs the start command signal to an electric device 3 concurrently serving as a motor and a generator, and the starting torque is applied to an engine 1. When the engine 1 is stopped, i.e., no signal is outputted from a crank angle sensor 12, for a fixed period or longer while the electric device (starting means) 3 is operated, an unsatisfactory start detecting means 21 detects it as the unsatisfactory start state, thereby a start action control means 22 continues/ discontinues the torque applying action in the positive rotation direction of the engine 1 by the electric device 3, a piston is swayed between the top dead point side and the bottom dead point side, and a warm lock or the like is dissolved. Startability can be improved accordingly.
